One of the salient features of Drupa 200O, part of the digital printing technology on Drupa 2O00, is digitization. That is, last year, each manufacturer began to use such a buzzword: "Drupa 2000 will be the first truly digital Drupa. Some technologies have come a long way since the last exhibition in 1995. One of them is inkjet printing. People have used inkjet printing to add variable information to labels and documents for more than 20 years. Now the quality of inkjet printing has improved and it has become faster. This time, Israelâ€™s Aprion company demonstrated color inkjet printing, which is âˆ·î‹²îƒ¦îŽå•ƒâˆˆè¹¦è‹¡000 square feet. Can be widely used in packaging areas such as corrugated cartons, display products, and high value-added cartons. Because the workflow is all digital, it is particularly suitable for on-demand delivery. In theory, it can be used for color newspaper printing. Aprion has agents and users in the United States. During Drupa, Aprion and Lasercomb of Germany announced that Lasercomb was designated as the sole agent in Europe to sell sheetfed ink jet printers for corrugated paper printing. The machine has a printing width of 65 inches and prints 200 square meters per hour (400 square meters in monochrome) when printed in full color at 6O0 dpi. Lasercomb is a company that manufactures packaging designs and laser die-cutting equipment. It operates in more than 50 countries and is therefore well-suited for this type of agency. Perhaps printing using "heavy metal" technology faces challenges from this aspect. However, other companies will not wait for it. At this exhibition, there were only 13 manufacturers of digital offset presses. This new wave of digital offset press makes people excited. The worldâ€™s largest manufacturers of four traditional offset presses are Heidelberg, Roland, KBA, and Komori. According to these four companies, they account for 80% of the worldâ€™s offset press market. All these have entered the digital offset press market. However, Xerox has developed rapidly in the printing market. According to Xerox, its sales rank second among printing equipment manufacturers, second only to Heidelberg. Most digital offset press manufacturers use CreoScitex and Presstek's digital offset press technology. Unlike traditional offset presses, digital presses transfer digitized files to a plate already on the press before starting printing. This simplifies the job of the printing shop, can change the content at the last minute, shorten the cycle, and increase the reliability. According to CreoScitex, a short print run with 500 prints is still economical. You can use a wide range of papers and use spot colors. With the CreoScitex imaging system, the offset version mounted on the press can be plated within four minutes, regardless of the resolution. Thanks to the integrated Brisque and Prinergy digital workflows, high output can be guaranteed. The CreoScitex imaging system on Drupa 2000 includes the Speedmaster 74 DI in Heidelberg, the 74 Karat in the KBA-Singapore Joint Venture, the Project D in Komori and the Dico Web in Manroland. The Speedmaster 74 DI has achieved commercial success and can achieve six colors, flip printing and glazing. 74 karat only requires the operator to have less offset experience. Komoriâ€™s Project D wants to open the digital offset press market. And Roland's DicoWeb has been installed in the user's factory, which will lead to a revolution in printless printing. In addition to patents such as convertible glazing presses, CreoSctex has begun to engage several printer manufacturers to enable them to understand unprinted offset technology. CreoSctex's SPTM production process includes the installation of a reusable material on the plate cylinder of the press, a transferable medium sprayed onto this material, which can then be imaged using CreoScitex SQUARE 5pot thermal imaging technology. After the printing is completed, the media can be wiped off to apply a new coating to the next job. All of this is done on the press without the need for traditional plates. Drupa's Quickmaster DI in Shanghai, Germany, was the first manufacturer of offset presses to use Presstek's on-press imaging technology in 1995. More Drupa 2000 manufacturers have adopted Presstek's new on-board imaging technology. For example, Xerox, Adast, Unibby and others. The Artest and Xerox divisions use Presstek's PAX DI technology. Unibig uses Presstek's DI plate and uses Presstek's ProFire on-press imaging technology in a four-color printing press on one cylinder, while Presstek's PearDry media is used on the press. The imaging time is 2.5 minutes at a resolution of 1270 dpi and 5.5 minutes at a resolution of 2540 dpi. Uniby's 340-DI is for commercial printing, prepress and in-unit printing. Presstek also announced that it has partnered with Didde to produce the first DI UV web-to-plate printer. Presstek said that according to the user's response, the current trend is that the print volume is between 2OO and 40,000, and the future will grow to between 100 and 70000. Xerox's DocuColor 206O digital sheet-fed color printer can print 60 sheets per minute at a cost of 10 cents each. The same type of machine also has the Docu Color 2405, which prints 45 sheets per minute and the quality is close to offset printing. This machine is used for variable data printing and internet printing. Xerox's "digital blanket" technology has four photoreceptors that transfer images to printed materials, much like traditional offset blankets do. Indigo and the e-commerce company MediaFlex.com showcased a technology at the exhibition. Visitors can see soft proofs on the screen shortly after entering data and requests. After confirmation, this order was sent to Indigo's TurboStream press in Indigo's JLYL format. After a few minutes, the visitor received a four-color booklet and the content was printed exactly as the visitor requested. Using Indigo/MediaFlex.com's portfolio approach, users can combine Indigo's digital printing technology with the creation and ordering of online documents.

About the discussion of digital printing and offset printing What is the future of the printing industry? How does the industry face challenges? These challenges come from the international Internet, the need for faster and more flexible data transfer, faster job changes, and lower production costs. Will the printing industry be strongly "squeezed" in the coming years? Will television and radio lose viewers? Readers of print media will turn to the Internet? Will paper as a traditional information medium be replaced by new technologies such as e-paper, e-books and e-commerce? On May 23, 2000 in Drupa's press room Heidelberg representatives discussed with more than 50 technical journalists from 15 countries. The main points of view are summarized below: In enthusiastic discussions, the reporters agreed with most of the opinions and opinions of the representative of Heidelberg. Participants are confident that the printing industry will have bright prospects, predicting that Asia and Africa will have high growth rates. The desire for knowledge in these areas has spurred further demand for printing. Most reporters agree with Heidelberg's view that electronic paper and e-books will not replace or eliminate traditional media paper. Most people's evaluation of the Internet is that it brings opportunities for the printing industry. However, it is argued that the operators must protect their interests because the printing middlemen are taking away customers in the traditional printing industry on the Internet at a low price. Representatives from Heidelberg believe that traditional offset printing companies will not be harmed. This area has grown as usual. The first 5 days of Drupa are examples, during which we have completed 50% of the planned sales plan, users in this area are successful and offset printing is growing. The current installation rate for digital printing is less than one percent. However, it is expected that the growth rate of digital presses will be very high. For this reason, many companies are interested in digital presses. Companies that need these in advance need to digitize the entire work process first. Heidelberg's direct imaging has already taken the lead in this regard. We see users focus on digitizing the workflow. Digital printing helps these companies complete orders quickly and flexibly. Recent research in the United States shows that their income is above average. Their turnover increased by 42%. The confrontation between offset printing and digital printing is wrong. This does not fit Heidelberg's strategy. Heidelberg regards itself as a collaborator and provides users with various required programs. People need technical know-how and solutions. Various digital printing and digital offset printing are the features of the future printing industry. According to participants participating in the discussion, there will be no disagreement between simulation and digitization. Optimizing production through low-volume printing and non-contact printing is gaining more and more market share. Both methods can meet the needs of on-demand printing and rapid replacement of products. There is no contradiction between direct imaging and other technologies. We provide solutions based on digital workflows that ensure that users receive high quality products in the shortest possible time. Heidelberg uses a variety of user-friendly technologies, the most important being to provide the right solution for the right application at the right time. Middlemen took away the customers of the printing industry at a low price, which poses a threat to the printing industry. Heidelberg naturally disapproves of this. But in general, the electronic service still offers a lot of opportunities and printing also has experience in dealing with new technology changes and challenges. Desktop publishing in the 1980s and 1990s is an example. Products, solutions, and know-how are required, but ultimately the user decides which business strategy is right. We are moving from offset to hybrid production, offset printing plus digital printing or offset printing. A basic example of Heidelberg's hybrid solution is the color pre-printing on the Quickmaster 46 DI followed by personalised printing on the Digimaster 9110. The Internet and so-called dotcom companies are affecting the printing industry. However, the growth of the Internet has also contributed to the growth of the advertising industry. For example, dotcom invests heavily in advertising, and the advertising industry profits from it. At the same time, the Internet provides a digital infrastructure that makes ordering among companies better, faster, and more efficient. The Heidelberg representative suggested that companies could pull customers through their web pages and use the web as a platform for printing. The Internet will change many things, but at the same time it also facilitates and increases orders and lowers prices. Whether for small, medium or large printing companies, the Internet is an opportunity. Heidelberg supports users entering e-commerce. And in the weeks following Drupa 2000, users are provided with software for this purpose.
